ADJUSTABLE COVER FOR HOLDING PAMPHLETS, MAGAZINES, OR SHEETS.

SPECIFICATION forming part of Letters Patent No. 342,326, dated May 25, 1886.

Application filed January 25, 1886.

To all whom, it may concern:

Be it known that I, JAMES E. BRIGGS, a citizen of the United States, residing at Rochester, iu the county of Monroe and State of New York, have invented a new and useful Improvement in Adjustable Covers for Holding Pamphlets, Magazines, or Sheets otherwise Unbound, for Preservation and Temporary Use; and I do hereby declare that the following is a sufficiently full, clear, and exact description of the invention, and will enable others skilled in the art to which it pertains to make and use the same.

It consists of a sheet of binders board of the proper size for a cover to any given pamphlet or part of a volume, covered and lined with any ordinary book-cover materiahwhieh cover and lining is extended beyond the limits of the board to such an extent on the side at the left of the board as it lies outside up as will constitute in itself a flexible back and cover for the opposite side of the pamphlets or sheets contained, the pamphlets and sheets being held in place by a rubber band, C, as

shown in Figure 3, the rubber band or other strap or string inclosing the whole, either lengthwise or widthwise of the page,in a way that will admit of partial, if not entire, reading of the page without removal, and of easy access to the pagination, as well as easy re moval of pages or numbers.

Serial No. 189,637. (No model.)

Fig. 1 represents the cover open outside up, A being the stiff portion of the cover, and B the back and flexible portion. Fig. 2 is intended to represent the same inside up and in position for inserting the pamphlet or sheets, A being the stiff cover, and B the flexible. Fig. 3 represents the cover in use, 0 being the rubber or other strap; D, the pamphlets or sheets, and B the flexible portion of the cover adjusting itself to any thickness.

These covers are made of any ordinary bookcover material, according as they are needed for very temporary or permanent use.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-

An adjustable temporary pamphlet and sheet holder or cover consisting of one stiff cover of the ordinary book-cover style, the covering of which is extended to make aflexible back and opposite cover orflap, to constitute, when in use, an expansive back, binder, or cover, adapting itself to any thickness of contents, secured in place by rubber band or other strap or tape in such a way as to allow the contents to be consulted without removal.
